Fast Mesh Winding Number extension to aTMeshAABBTree3. This class is an "add-on" to the AABBTree, that can compute the Fast Mesh Winding Number. This calculation requires a precomputation pass where information is cached at each tree node.
template<class TriangleMeshType> class TFastWindingTree
int
FWNApproxOrder
FWN approximation order. Must be 1 or 2. 2 is more accurate, obviously.
double
FWNBeta
FWN beta parameter - is 2.0 in paper
